|

|
||||
* aclocal.m4 (--enable-sim-hostendian): New option. Allow the
|
||||
host endianness to be overridden.
|
||||
(--enable-sim-endian): Allow the target platform's byte order
|
||||
to be overridden.
|
||||
(--enable-sim-inline): Control the inlining of common components.
|
||||
(--enable-sim-bswap): For compatibility, also define WITH_BSWAP.
|
||||
(--enable-sim-warnings): Enable additional GCC compiler checks.
|
||||
* Make-common.in (SIM_ENDIAN, SIM_HOSTENDIAN, SIM_INLINE,
|
||||
SIM_WARNINGS): Add.
|
||||
|
||||
* sim-n-core.h, sim-n-bits.h, sim-n-endian.h: Rename from
|
||||
sim-*-n.h so that the names are uniq on dos machines
|
||||
* sim-core.c, sim-bits.c, sim-endian.c: Update.
